Fort Denison is home to a wealth of historic heritage. The Fort Denison heritage collection project invited volunteers to locate, identify, document, conserve, interpret and make accessible the heritage collections in Sydney Harbour National Park. This allowed NPWS to engage with the community and ensure our collections are protected.
